VCC_5V_EN
O
5V Voltage Power Supply Enable:
Enable for 5V
power rail.
SYS_PGOOD
O
System Power Good Indication:
Asserted by FPGA
to system when all power supplies are valid.
Clock Configuration
CLOCK2_SSPCS1
O
SPI Chip Select Enable:
Connected to Clock
Generator SPI_LE pin. Falling edge of SSPCS1
initiates a transfer. If SSPCS1 is high, no data
transfer can take place.
CLOCK2_SSPCK
O
SPI Serial Clock:
Connected to Clock Generator
SPI_CLK pin. FPGA SPI bus clocks data in and out
on the rising edge of SSPCK. Data transitions
therefore occur on the falling edge of this clock.
CLOCK2_SSPSI
O
SPI Serial Data MOSI:
Connected to Clock
Generator MOSI pin. This signal is used for serial
data transfers from master (FPGA) output to slave
(CDCE62005) input.
CLOCK2_SSPSO
I
PU
SPI Serial Data MISO:
Connected to Clock
Generator MISO pin. This signal is used for the serial
data transfers from slave (CDCE62005) output to
master (FPGA) input.
REFCLK2_PD#
O
CLOCK Generator Power Down:
Places Clock
Generator into power down state forcing the
differential clock output into high-impedance state.
UCD9222 Interface :
UCD9222_PG1
I
UCD9222 Power Good Indication for CVDD DSP
Core Power:
Indicates that CVDD DSP core power is
valid.
UCD9222_ENA1
O
UCD9222 Enable for CVDD DSP Core Power:
Enables CVDD DSP core power rail.
UCD9222_PG2
I
UCD9222 Power Good Indication for VCC1V0 DSP
Core Power:
Indicates that VCC1V0 DSP core
power is valid.
UCD9222_ENA2
O
UCD9222 Enable for CVDD DSP Core Power:
Enables VCC1V0 DSP core power rail.
PGUCD9222
I
UCD9222 Power Good Indication:
Indicates both
DSP core supplies - CVDD and VCC1V0 are valid.
UCD9222_RST#
O
UCD9222 Reset:
An active low signal will reset
UCD9222 device.
PM BUS : (RFU)
PMBUS_CLK
O
PM Bus Clock:
FPGA provided clock source on PM
bus.
PMBUS_DAT
I/O
PM Bus Data:
A PM Bus slave device can receive
data provided by master (FPGA), or it can also
provide data to master (FPGA) via this signal line.
PMBUS_ALT
I
PM Bus Alert:
A PM Bus device may notify the host
(FPGA) via this signal if a fault or warning is detected.
PMBUS_CTL
I
PU
PM Bus Control:
Used to turn on/off the device in
conjunction with UCD9222_ENA1 / UCD9222_ENA2
pins.
PHY Interface :
PHY_INT#
I
Interrupt Request from 88E112 PHY (RFU)
